I think the skins collabs for Overwatch are cool and they work really well so, im gonna put a bunch of what i would like and we could complete a list of cool colabs together so maybe one day blizzard sees this and know what we want.
-Warhammer colab would be awesome just imagine a Reinhardt as a Space marine and idk maybe an ork Doomfist or a necron Echo, and warhammer is getting a lot bigger rn
-Fallout Serie colab, reinhardt as maximus, Cassidy as the Goul and Tracer as Lucy, just perfect
These are just some examples that i would like dont doubt in keep adding to the list and make something together
